This trial is investigating whether low- and high-ED foods are substitutes for each other. They will do this by looking at how much of each food people eat in a meal when the meal has different proportions of low- and high-ED foods.

Who is the study for?
This study is for healthy adults aged 18-35 with a BMI of 18.5 to 24.9 who enjoy a variety of foods like soup, pudding, and snacks, eat breakfast before 10 am, are not on appetite-affecting meds or have eating-related medical conditions, and can finish the sessions in under 8 weeks.Check my eligibility
What is being tested?
The trial tests if low-energy-density (low-ED) foods can replace high-energy-density (high-ED) ones in meals to help with weight loss. Participants will eat meals with varying ED levels over four sessions to see how their food intake adjusts.See study design
What are the potential side effects?
Since this trial involves common foods without any medicinal interventions, no direct side effects are expected from participating beyond potential changes in dietary habits.
